- 2. A value that remains unchanged throughout an equation or mathematical relationship.
- 3. The process of simplifying a radical involves finding the simplest form by reducing the radicand or rationalizing the denominator.
- 5. The number written above the radical symbol, indicating which root is being taken (e.g., the index of a square root is 2).
- 6. The number or expression under the radical symbol (the square root or cube root sign) is referred to as the radicand.
- 8. The process of eliminating radicals from the denominator of a fraction by multiplying the numerator and denominator by an appropriate expression.
- 9. A statement that two ratios or fractions are equal to each other.
- 11. A type of variation involving more than two variables, where the outcome depends on the simultaneous variation of multiple factors.
- 13. Root The square root of a number is a value that, when multiplied by itself, gives the original number.
- 14. A number that cannot be expressed as a fraction or ratio of two integers is considered irrational. Irrational numbers have non-repeating, non-terminating decimal representations.
- 15. A number written as a superscript that indicates how many times a base should be multiplied by itself (e.g., in √x, the exponent is 1/2).

- 1. A mathematical relationship where a quantity changes both directly and inversely with multiple variables.
- 4. A relationship between two variables where their values increase or decrease proportionally.
- 7. A relationship between two variables where their values change inversely or opposite to each other.
- 10. An equation containing one or more radical expressions.
- 12. Root The cube root of a number is a value that, when multiplied by itself twice, gives the original number.
